In the case of a search engine, the problem is how to find the most relevant webpages for this particular set of keywords”. The algorithm is how Google finds, ranks, and returns the relevant results”.

In 2013, the Hummingbird algorithm was a major change in order to deliver more targeted results for users.


Before going deep into important algorithm updations of google, lets go through history of google.

History of Google

Google was started in March 1996 as a research project by Larry Page and Sergey Brin when they where Ph.D. students at Stanford University,California. The conventional search engines ranked results by counting how many times the search terms appeared on the page. Then new technology called pagerank was introduced. It determined a website’s relevance by the number of pages, and the importance of those pages, that linked back to the original site. It was first named as backrub because the system checked backlinks to estimate the importance of a site. They changed the name to Google, originating from a misspelling of the word “googol. Googol is the number one followed by one hundred zeros. Google’s original homepage had a simple design.

Why Google Algorithm Updates was started?

Initially very little was needed to fully optimize a site. All we have to do is optimize the page content. The inverse relationship between query position and weight, simply boiled up by putting ones important keywords higher on the HTML tag hierarchy. This was relatively simple algorithm. So webmasters quickly discovered tricks to vastly boost their SERP. They started practicing link keyword stuffing on page content. As a result, google removed these sites from its index. They started to practice this to punish disingenuous webmasters looking to cheat the system. Each year Google changes its search algorithm about 500-600 times.
